Apparently my rear shock doesn't like the cold. It lost all the air from Topeka to Lawrence,KS! I got .75mi in before I realized something mechanical wrong. I could feel my saddle was lower but since I was layered up like Ralphies lil brother in Christmas Story I didn't see the issue immediately. Got 1.5 mi in and my Camelbak is frozen solid. Fingertips and toes close to froze too. I'm still calling it a victory. I didn't quit today, my bike did! I can't help that my bike it a Diva.
